A) Concentric air/flue ducts for roof outlet with PP
outlet inner, ø 60/100 mm
B) Lead flashing roofing tile
C) Vertical flanged concentric compression fitting ø
60/100 mm with taps for air/flue drawing and PP inner
duct, silicone lip gaskets and neoprene gasket.
The vertical terminal can be connected to a coaxial
air/flue duct (ø60/100 mm) having also an horizontal
part. The maximum total length of the duct should be 4
m + 2 bends or 5 m without bends.
After positioning the boiler on the wall, cut a ø120 mm
hole in the ceiling corresponding to the boiler upper inlet
connection.
Before installing the air/flue kit definitively on the roof,
the Ø100 and Ø60 ducts can be cut at the required
dimension respecting the minimum distance as the
figure shows.
Insert the ø100 mm duct into the ceiling hole which is
supposed to be fixed with mortage. Adjust the lead
flashing to the roofing tiles or bent tiles. Fix the vertical
flanged compression fitting (C) to the boiler by means of
the screws using suitable silicone gaskets.
Insert the ø60 inner duct into the flanged compression
fitting after fixing the inner ø60 mm silicone gasket.
Then place the outer ø100 duct in the same way.
In the event that concentric ducts and/or bends are necessary to connect the terminal duct
(A) to the flanged compression (C), the firm hold must be guaranteed by applying suitable
silicone rubber gaskets inside the spigot and socket joints. Use original accessories only.
Every horizontal or vertical item is to be fixed to a suitable support wall or ceiling.
Never obstruct the boiler air/flue ducts, even provisionally. Professionally qualified
personnel are supposed to check the draught efficiency and the combustion product hold.
